Embodiment Construction

[0028] A method for controlling the emergency fan speed of a fan aircraft, comprising the steps of:

[0029] S1: The controller judges the failure of the rudder surface of the fan-wing aircraft;

[0030] S2: If the judgment result of step S1 is the failure of the elevator in the single rudder surface failure, then execute the first control scheme;

[0031] S3: If the judgment result of step S1 is that the aileron rudder failure in the single rudder surface failure, then execute the second control scheme;

[0032] S4: If the judgment result of step S1 is a rudder failure in a single rudder surface failure, or a lateral failure in a plurality of rudder surface failures, execute the third control scheme;

[0033] S5: If the judgment result of step S1 is the longitudinal and lateral faults among the plurality of rudder surface faults, execute the fourth control scheme.

[0034] The fan-wing aircraft mainly has 5 control variables: aileron rudder δ a , elevator δ e , rudder δ ...

Abstract

The invention discloses a method for controlling rotating speed of an emergency fan-wing of a fan-wing aircraft, and relates to the technical field of fan-wing aircrafts. The method comprises the following steps that firstly, a controller is used for judging the fault of the rudder surface of the fan-wing aircraft, if the judgment result is an elevator fault in single-rudder-surface faults, a first control scheme is executed; if the judgment result is an aileron rudder fault in single-rudder-surface faults, a second control scheme is executed; if the judgment result is a rudder fault in the single-rudder-surface faults or a transverse lateral fault in a plurality of rudder surface faults, a third control scheme is executed; and if the judging result is the longitudinal and transverse lateral faults in the plurality of rudder surface faults, a fourth control scheme is executed. According to the method, the low efficiency or fault phenomenon of the fan-wing aircraft operating the ruddersurface can be coped well with, and safe and stable flight of the fan-wing aircraft is ensured.

Description

technical field [0001] The invention relates to the technical field of fan-wing aircraft, in particular to the technical field of a method for controlling the emergency fan-wing speed of the fan-wing aircraft. Background technique [0002] The fan-wing aircraft is a new-principle new-configuration aircraft that embeds a cross-flow fan on the leading edge of a large thick wing, and provides lift and thrust at the same time through the rotation of the fan. It is a low-speed and heavy-load aircraft between helicopters and fixed-wing aircraft. Due to the simple structure and control of fan-wing aircraft, it has the advantages of high flight efficiency, high load, low noise, and ultra-short take-off and landing. It has gained great development advantages in civil and military use, and has become a new research hotspot in the field of aircraft in recent years. At present, fan-wing aircraft can already complete remote control flight, but the research hotspots of fan-wing aircraft ...
